So my 2005 sv650 with 12,000 on the clock randomly started giving me an issue today.
I rode about 10km to downtown to try and get a tag in the mc tag game, and had no problems whatsoever. The bike was then turned off for about 1/2 hour, and when I started riding it again, I noticed it was hesitating a bit as I was stopped at red lights. I kept rolling and the bike seemed fine under load as I rolled around in downtown traffic, once the revs were up.
As I worked my way back out of town, the idle issue was getting worse....bad enough that I had to keep a little throttle rolled on while I was stopped for fear of it conking out altogether. It did die on me a couple times at lights but I was able to start it up again.
Once I got out of downtown and into a bit more open road, I was able to actually roll on a bit of throttle. When I rolled it on hard, the bike hesitated again.
I rode home like this, and near my house I gave it a bit of throttle again and it seemed fine this time, and then once I was outside my house the idle seemed slightly burbly, but it wasn't dying altogether.
I did ride through a fairly significant amount of rain last night....could it be related to this? Again, the bike gave no issues on the way downtown, only on the way back home.
